I was thinking about upgrading to an GTX 680 or another 7850 for cross fire,and an i5 4670k but I'm not sure if that's really necessary. If you think I should consider upgrading please let me know any budget parts that would give me a good price/performance ratio.Thanks.
Do you have any problems currently with the games you play? If no, then don't upgrade.
They are running at about 60fps on high 1920x1080 resolution but does that really determine the effect next gen games will have on my pc ? I cant play games that haven't released yet, I'm just wondering if I will have to set all my graphical settings to low or even lower my resolution when games like watch dogs or maybe even GTA V release. I prefer to have my games at high/ultra with around 50-60 fps with 1920x1080 resolution so if I have to resort to lowering my settings for performance I'd just rather spend some money to upgrade.
Honestly, there's no point in wasting money in trying to future proof your system because it will eventually get out-dated and then you'll have to waste even more money. I'll just wait until you actually need to upgrade.
